Start by gathering all your ingredients. Chop the onion and celery, and measure out the spices.
In your crock pot, add the chopped onion, celery, cream of chicken soup, chicken broth, poultry seasoning, garlic powder, and black pepper. Stir until everything is well combined.
Place the boneless, skinless chicken breasts directly on top of the mixture. Don’t worry about stirring them in; they will cook down perfectly.
Cover the crock pot and cook on low for 6-8 hours, or on high for 3-4 hours. The longer you cook it, the more tender the chicken will be.
Once the cooking time is up, remove the chicken breasts and shred them using two forks. Return the shredded chicken to the crock pot and stir to combine.
Open the can of refrigerated biscuits and cut each biscuit into quarters. Gently fold the biscuit pieces into the mixture in the crock pot.
Cover and cook on high for an additional 30 minutes, or until the dumplings are fluffy and cooked through.
Spoon the chicken and dumplings into bowls and enjoy this warm, comforting meal with your loved ones.
